A J-star name is needed for the Consensus Layer upgrade after the I-star upgrade.
The consensus layer uses star names for upgrades whilst the execution layer uses Devcon cities. See: Post-Merge Network Upgrade Naming Schemes
Recent upgrade names:
Shapella (Shanghai + Capella)
Dencun (Cancun + Deneb)
Pectra (Prague + Electra)
Fusaka (Fulu + Osaka)
Glamsterdam (Gloas + Amsterdam)
Hegotá (Heze + Bogotá)- (I-star name for Consensus Layer upgrade after Heze + Devcon city name for Execution Layer upgrade after Bogotá)
Assuming a cross layer upgrade, any J-star name will be combined with an execution layer name in a portmanteau (Portmanteau generator), so any name choice should also consider this.
